How do I premanantely delete music in iTunes I have an iPhone 4s?

In iTunes and on the phone are 2 different things. In iTunes just delete them from the music folder. Then next time you sync the phone (if those same songs were in a playlist) they should go away from the phone too. Otherwise just delete tracks from your playlist in music on the phone--not in iTunes on the phone. Best luck.
